European Directive 2002/49/EC of 25 June 2002 on the assessment and management of environmental noise entails for EU Member States an assessment of environmental noise in the vicinity of major transport infrastructure (land and air) and in large agglomerations.
This assessment is carried out in particular through the development of strategic ‘so-called’ noise maps.
These maps are intended to be reviewed and revised every 5 years.The first
series were developed in 2007 (1st deadline) and 2012 (2nd maturity).
2017 is therefore the year of the 3 rd deadline.
CBS are required, in particular, for rail infrastructure with more traffic than
30 000 train crossings per year.;
For major road and rail transport infrastructure, the CBS shall be established, adopted and approved under the authority of the Prefect of the Department:
the Noise Card Approval Order is dated November 16, 2018
Noise maps are developed according to the indicators established by the European Directive, namely Lden (Day Evening Night Level) and Ln (Night Level).
• Day/day:
[6h-18h]
• Evening/evening:
[18h-22h]
• Night/night:
[22h-6h]
The Lden and Ln indicators correspond to a defined energy average over the periods (Day/Black/Night) for Lden and (Night) for Ln.
The corresponding results are expressed in A or dB(A) weighted decibels.
Noise-exposed areas (type C map) represent areas where limit values are exceeded:
Lden Index >73 dB(A)
Index Ln > 65 dB(A)

Some basic informations about API Store ®.
Operation and development of APIs are currently fully funded by company Apitalks and its usage is for free.
Yes, you can.
All important information such as time of last update, license and other information are in response of each API call.
In case of major update that would not be compatible with previous version of API, we keep for 30 days both versions so you will have enough time to transfer to new version. We will inform you about the changes in advance by e-mail.
